2.2 Switching the Display On and Off
If you have a combined Radar/Chartplotter, the factory default power-up mode
is radar. Once you have used the display unit it powers-up in the last used mode.
The following sections describe the power-up sequence for radar and chart
mode, how to adjust the lighting controls, and how to select simulator mode.
Radar Mode
This section explains how to switch the radar display and scanner on and off,
and how to switch the scanner between Transmit, Standby and Scanner Off
mode.
You normally operate your radar in transmit mode, but you can use the display
unit without the scanner operating as follows:
Standby mode : You should use this mode when you are not operating the
radar for short time periods. The scanner does not transmit and
the antenna does not rotate, so the radar uses less power.
However, the scanner remains powered so when you return to
transmit mode, the magnetron does not need to warm up.
Scanner off mode : You should use this mode when you do not require the
radar, but you are using the display unit say, for chart data or
data from another source.
Scanner off mode removes power from the scanner.

To switch the Radar on, press and hold the
POWER
key until the unit beeps.
The keys light up, the display shows the start-up information as illustrated
below, and the radar starts the magnetron
warm-up sequence.
